SHIELDS, EENNSYL-VANIA, ASSIGIJOR TO THE PHOENIX GLASS GUI EPA Y, 015 B'LGNACA, PENNfSYLVANIA, A CORPORATEQ'N OF YVES'I VIRGINIA SEGN GLOBE Application filed October 26,1832. Serial No. 639,609.

My invention is hereinafter described as applied to sign globes of canteen-likeform,but it will be understood that it is applicable also to various other types of structures wherein face plates or the like are employed.

One object of my invention is to provide a globe structure of such form that there will be proper seating between the faceplate and the body, notwitastanding irregularities of con- 19 tour in either the plate or the globe, such as occur during the process of manufacturing, through uneven shrinkage, etc.

Another object of my invention is to pro vide a structure of the character referred to 5 wherein a snug fit will be maintained between the face plate and the body to which it is applied, notwithstanding the frequent changes in temperature, and consequent expansion and contraction.

Another object of my invention is to provide a structure of the character described, wherein danger of moisture or dust entering between the face plate and the globe body is reduced to a minimum.

Another object of my invention is to provide a globe structure of generally improved form.

In the accompanying drawing, Figure 1,

is a face view of a sign globe constructed according to my invention; Fig. 2 is a vertical sectional view thereof, and Fig. 3 is a fragmentary sectional view, on an enlarged scale, taken on the line HII1I of Fig. l.

The globe body 4 may be formed in any suitable manner, with flattened or only slightly convex sides. These sides may be continuous, as indicated at 5, or may be cut out as shown at 6, or one side may be left continuous and the other out out, as indicated in my application, Serial No. 423,035, filed January 24, 1930 (now Patent No. 1,883,065). As set forth in the said application, the cutting out of one side permits more convenient access to the interior of the globe for the purpose of decorating the inner surfaces thereof. Also, if the globe is of white glass or other color, instead of clear glass, it may be desirable to cut out the sides or faces of the globe in order to permit freer passage of light through the face plates 7.

These face plates will be lettered and decorated preferably on their inner or rear surfaces, so that the decoration will not be ex posed to the elements, and hence not so subject to deterioration, discoloration, or accumulation of dirt.

The globe has annular recesses formed therein at the vicinity of the edges of the face plates 7. Herctofore, edges of face plates have been cemented inplace, but the cement will in time crack and become porous, so that moisture may pass therethrough to the inner sides of the face plate, carrying with it dust and otherforeign matter which will discolor the globe, and in some cases the moisture which enters at the top of the globe will accumulate in the lower portion thereof behind the face plate, to cause a more aggravated condition of stain and discoloration on the face and adjacentsides of the globe, in addition to which the collected moisture may freeze, and cause the face plates to be broken.

An annular or substantially annular seating ring 8 is interposed between the edge of each face plate and the groove or shoulder in the globe body. These rings are preferably of spring-like material such as a copper alloy, aluminum, or other sheet metal, so that they will yield when the face plates are clamped in position by means, such as bolts 9. The

bolts 9 are shown as having springs 10 interposed between the nuts and the adjacent wall of the globe, but these springs may be dispensed with when the rings 8 are employed, and the nuts can be screwed tightly up against the globe wall.

Each seating ring 8 has a flan e portion 11 that bears against the side of the globe, and a lip portion 12 that overlies the edge of its associated face plate 7. The flange 11 not only provides for a desired degree of yieldability, but serves to form a groove along which moisture may be conducted from the upper portion of the globe to the lower portion thereof, and thereby prevented from entering behind the face plate. Similarly, the lip 12 serves to prevent moisture entering behind the faceplate. To still further seal the structure against access of moisture, I provide a gasket ring 13 of cork, rubber,

asbestos, or other suitable material, and a similar ring can be provided behind the flange 11, if desired.

The seating ring 8 is highly yieldable, and besides serving as a seal and a shield against access of moisture to the interior of the globe, its yielding nature permits it to have continuous lines of contact with the side of the globe and the face plate, since it will automatically adapt itself to irregularities in the globe and the face plate when the bolts 9 are secured in place. These irregularities may occur during the manufacture of the globe and the face plate, or through uneven contraction thereof, during cooling and annealing. Furthermore, the close-fitting lines of engagement will be maintained notwithstanding expanding and contraction through changes in temperature of the globe when in use.

It will be understood that in some cases, I may prefer to cut out one face of the globe, and after decoration thereof apply a face plate 7 to the side, leaving the other side of the globe intact and decorating it interiorly, thus rendering it unnecessary to apply a face plate to the second-named side.

I claim as my invention 1. The combination with a globe body having a peripheral portion and a side wall, the peripheral portion being extended to partially overlie the sidewall, of a substantially annular seating ring disposed against the side Wall along a line adjacent to the inner boundary of the said overhanging portion, and having an outwardly-exposed groove, a face plate, and means for securing the face plate against the outer side of said ring.

2. The combination with a globe body, of a face plate, a substantially annular seating ring of V-form in cross section, disposed against a vertical face of the globe and with its channel outwardly exposed, one flange of the ring abutting the globe and the other flange abutting the inner surface of the face plate and having an angular extension overlying the edge of the face plate, and means for securing the face plate to the globe body.

3. The combination with a globe body having a sidewall and a peripheral portion extended to partially overlie the side wall, of a face plate, a substantially annular seating ring ofV-form in cross section and with its channel outwardly exposed, one flange of the ring being disposed against the side wall, along a line adjacent to the inner boundary of said overhanging portion, and the other flange ,abuttin" the inner surface of the face plate and having an angular extension overlying the edge of the face plate, and means for securing the face plate to the globe body.

In testimgmy whereof I, the said ANDREW H. :linwriirr have hereunto set my h and.
